Non Destructive Testing (NDT)

By means of nondestructive testing (NDT) hidden defects can be identified in a variety of goods reliably before commissioning. In this way we protect the consumer from damage which could result from the unexpected failure of such products In the meantime NDT has become an essential tool in quality control.

Examples

]

Flaw detection

  • Pulse-Echo method
  • Transmission method
  • Resonance technique
  • TOFD Technique
  • Phased Array Technique
  • Acoustic emission
  • Ultrasonically inducted thermography
  • Ultrasonic holography
  • Ultrasonic tomography (i.e.: measurement of the thickness of hardened layer)
]

Leak detection

]

Evaluation of material quality (mechanical parameters, homogeneity)

]

Measurement of thickness of hardened layer and differences in mechanical parameters in a solid block

]

Measurement of material thickness

  • Measurement of thickness and bonding quality of layers on paper and foils
  • Measurement of layer of paint on coated surfaces
]

Evaluation of joint quality:

  • Delamination flaws
  • Glued connections,
  • Welds, point welds
    • 100%- weld testing of plastic packages
    • with contact (e.g. plastic cups)
    • contactless with air ultrasound (e.g. plastic bags)
]

Evaluation of mechanical stresses

]

Measurement of geometry of objects

]

Detection of foreign bodies (plastic, rubber, wood,…)
